Serial No. 460,978. v

This invention relates to a sash pulley whereby a pair of window'sashes can be profvided with a flexible connection extending upwardly into the top of the frame so thatthe sashes will be balanced; and it becomes unnecessary to form the window frames with.

' pockets or boxes such as commonly employed where sash weights are .used. r v

It is another obj eet of the invention to provide a pulley whichzcan be positioned read ily in the upper portion of a'window-frame,"

the fastening means employed for holdi'ng it in place being located where they are'accessible readily at all times so that the pulley can be removed and a new flexible connection placed in position without mutilating the frame. V "With the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described an d claimed, it being understood that changes in the precise embodiment of the invention '5 herein disclosed may be made within the j scope of what is claimed without departing from the spirit of the invention.

In the accompanying; drawing the pie ferred form of the invention has been shown. In said drawing V Figure 1 is a section through the toppor- 7 tion of a window frame showing a sash pul-t ley in position with a flexible sash connection mounted thereon. I Figure 2 is a section on line 2-2, Figure 1. Figure 3 is a perspective view of the sash pulley. Referring to the figures by characters of I reference, 1 designates a portion of a'window frame provided with the usual parting strips 2 forming guide channels 3 and 4 at the sides thereof in which the sashes 5 and 6 are adapted to slide. Holes 7 are cut in the top of the frame so as toopen into the upper ends of the channels 3 and 4. In'the drawing only one of these holes has been illustrated but it is to be, understood that one of them is to be located adjacent each side of the frame.

The sash pulleyincludes a corner bracket 8 which is so shaped as to fit snugly in the corner and is provided longitudinally of its top and side portions with channels 9 adapted to receive the adjacent portions of the parting strips 2.. A yoke 10 is extended from the angle portion of the bracket and has a grooved wheel 11 mounted to rotate therein. freely. Openings 12 are formed in the bracket so that a flexible connection 13 mounted-on the wheel 11 can work freely within these openings. Thisconnection is adapted to be secured to the respective sashes 5 and 6 so. that each will act as acounterbalance for the other.

When it is desired to attacha sash pulley I to the frame 1 a'hole is cut'into the top thereof as shown at 7 and the yoke 10 with connece tion 13 mounted on its wheel is inserted upwardly into. the opening until bracket 8 becomes seated snugly in the-corner of the frame with the parting strips 2 in the chan nels' 9. The bracket is then fastened in place by means of screws 14 or the like inserted into the. side and top of the frame and after the connection 13 has been attached to the respective sashes the device is ready for use. The fastening devices ll can be easily reached for the purpose of detaching bracket '8 and withdrawing yoke 10 and wheel 11 from the opening 7.

What is claimed is:

1. A sash pulley including an angle bracket channeled in two directions for the reception of the top and side parting strips of a window frame, there being openings in the corner portion of the bracket atopposite sides of Y the channels, and a wheel supported above and between the openings and joined to-the bracket. 1

The. combination" with a Window frame having parting strips and an opening ex- J tending into the top of the frame at one corner thereof, of a corner bracket fitted snugly within the frame and straddling the parting strips a structure integral with the bracket and extending into the opening, a. Wheel carried by said structure for supporting a flexible sash connection, and means for securing the bracket to the frame to support the Wheel within the opening, there being openingsyin the bracket for receiving the flexible sash connection In testimony thatl claim the foregoing as my own I have hereto aflixed mv signature.
